Artemis IV
Artemis IV is a planned mission of the NASA-led Artemis program. The mission is proposed to include the fourth use of a Space Launch System (SLS) launch vehicle, sending an Orion spacecraft with four astronauts to the Lunar Gateway space station, where they will install the I-Hab module on Gateway, and conduct the second lunar landing of the Artemis program. Overview The mission will deliver and install the International Habitation Module (I-Hab) of the Lunar Gateway space station. I-Hab is being developed by the European Space Agency and the Japanese space agency JAXA. The mission will dock I-Hab to the first Gateway elements, the Power and Propulsion Element and Habitation and Logistics Outpost. After docking, astronauts will board a Starship HLS (HLS) vehicle also docked to the station. They will descend to the lunar surface in the HLS lander for a multi-day site inspection. Artemis IV will be the first flight of the Block 1B version of the Space Launch System. For ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lunar Gateway
The Lunar Gateway, or simply Gateway, is a planned space station which is to be assembled in orbit around the Moon. The Gateway is intended to serve as a communication hub, science laboratory, and habitation module for astronauts as part of the Artemis program. It is a multinational collaborative project: participants include NASA, the European Space Agency (ESA), the Japan Aerospace Exploration Agency (JAXA), the Canadian Space Agency (CSA), and the Mohammed Bin Rashid Space Centre (MBRSC). The Gateway is planned to be the first space station beyond low Earth orbit. However, the Second presidency of Donald Trump, Trump administration has called for ending the Gateway program in its 2026 budget proposal. The science disciplines to be studied on the Gateway are expected to include planetary science, astrophysics, Earth observation, heliophysics, Astrobiology, fundamental space biology, and Health, human health and performance. As of April 2024, construction is underway o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

List Of Artemis Missions
The Artemis program is a human spaceflight program by the United States. The Artemis program is intended to reestablish a human presence on the Moon for the first time since Apollo 17 in 1972; mid-term objectives include establishing an international expedition team, and a sustainable human presence on the Moon. Long-term objectives for Artemis are laying the foundations for the extraction of lunar resources, and eventually making crewed missions to Mars and beyond feasible. To date, missions in the program are aimed at exploration of the Moon, including crewed and robotic exploration of the lunar surface. These explorations will be more focused towards areas such as thlunar polesand thfar side of the moon Three flights of the Orion Multi-Purpose Crew Vehicle are currently planned for launch in the Artemis program in the early 2020s, beginning with Artemis 1. Before Artemis was named, the flights were referred to as "Orion missions". Numerous supporting scientific and technol ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
SLS Block 1B
The Space Launch System (SLS) is an American super heavy-lift expendable launch vehicle used by NASA. As the primary launch vehicle of the Artemis Moon landing program, SLS is designed to launch the crewed Orion spacecraft on a trans-lunar trajectory. The first (and so far only) SLS launch was the uncrewed Artemis I, which took place on 16 November 2022. Development of SLS began in 2011 as a replacement for the retiring Space Shuttle as well as the canceled Ares I and Ares V launch vehicles. SLS was built using existing Shuttle technology, including solid rocket boosters and RS-25 engines. The rocket has been criticized for its political motivations, seen as a way to preserve jobs and contracts for aerospace companies involved in the Shuttle program at great expense to NASA. The project has faced significant challenges, including mismanagement, substantial budget overruns, and significant delays. The first Congressionally mandated launch in late 2016 was delayed by near ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Super Heavy-lift Launch Vehicle
A super heavy-lift launch vehicle is a rocket that can lift to low Earth orbit a "super heavy payload", which is defined as more than by the United States and as more than by Russia. It is the most capable launch vehicle classification by mass to orbit, exceeding that of the heavy-lift launch vehicle, heavy-lift launch vehicle classification. Only 14 such payloads were successfully launched before 2022: 12 as part of the Apollo program before 1972 and two Energia (rocket), Energia launches, in 1987 and 1988. Most planned crewed Lunar mission, lunar and Interplanetary spaceflight, interplanetary missions depend on these launch vehicles. Several super heavy-lift launch vehicle concepts were produced in the 1960s, including the Sea Dragon (rocket), Sea Dragon. During the Space Race, the Saturn V and N1 (rocket), N1 were built by the United States and Soviet Union, respectively. After the Saturn V's successful Apollo program and the N1's failures, the Soviets' Energia launched twi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Trans-lunar Injection
A trans-lunar injection (TLI) is a propulsive maneuver, which is used to send a spacecraft to the Moon. Typical lunar transfer trajectories approximate Hohmann transfers, although low-energy transfers have also been used in some cases, as with the Hiten probe. For short duration missions without significant perturbations from sources outside the Earth-Moon system, a fast Hohmann transfer is typically more practical. A spacecraft performs TLI to begin a lunar transfer from a low circular parking orbit around Earth. The large TLI burn, usually performed by a chemical rocket engine, increases the spacecraft's velocity, changing its orbit from a circular low Earth orbit to a highly eccentric orbit. As the spacecraft begins coasting on the lunar transfer arc, its trajectory approximates an elliptical orbit about the Earth with an apogee near to the radius of the Moon's orbit. The TLI burn is sized and timed to precisely target the Moon as it revolves around the Earth. The bu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Exploration Upper Stage
The Exploration Upper Stage (EUS) is a rocket stage under development for future flights of NASA’s Space Launch System (SLS). Designed for use on the SLS Block 1B and Block 2 configurations, it will replace the Interim Cryogenic Propulsion Stage used on the Block 1 variant. The EUS will be powered by four RL10C-3 engines burning liquid oxygen and liquid hydrogen, generating a total thrust of . Its first flight is planned for Artemis IV in 2028. However, the Trump administration has proposed terminating the SLS program after Artemis III, which would eliminate the need for the EUS. Development The Block 1 configuration of the SLS, which first flew the Artemis I mission, has a core stage powered by four RS-25 engines, two Space Shuttle-derived five-segment solid rocket boosters, and an Interim Cryogenic Propulsion Stage (ICPS) upper stage. NASA is developing the EUS to increase SLS performance for trans-lunar injection beyond Block 1 specifications. The improved up ...

Interim Cryogenic Propulsion Stage
The Delta Cryogenic Second Stage (DCSS) is a family of cryogenic-fuelled rocket stages used on the Delta III, Delta IV, and on the Space Launch System Block 1 launch vehicles. The DCSS employs a unique two-tank architecture where the cylindrical liquid hydrogen (LH2) tank carries payload launch loads and forms the upper section. An oblate spheroid tank filled with liquid oxygen (LOX) and the engine are suspended from the LH2 tank and covered by the interstage during initial launch. The DCSS is powered by a single RL10B-2 engine built by Aerojet Rocketdyne, which features an extendable carbon–carbon nozzle to improve specific impulse. The DCSS was designed by the National Space Development Agency of Japan, based on the second stage it developed for the H-IIA rocket. The initial versions for the Delta III were built by Mitsubishi Heavy Industries in Japan. For the Delta IV, production was transferred to Boeing Integrated Defense Systems and later to United Launch Alliance. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
